Organic inputs from agroforestry trees on-farms for improving soil quality and crop productivity in Ethiopia
Indigenous agroforestry trees and shrubs on farmlands are an under-utilized resource that can be used as green manures (GM) to alleviate declining soil fertility and productivity. The aims of studies described in this thesis were to investigate: (1) the seasonal dynamics in chemical contents of foliage from selected tree species potentially available as sources of GM, (2) rates and patterns of ...

متن کاملDoes Participation in Farmer Field School Extension Program Improve Crop Yields? Evidence from Smallholder Tea Production Systems in Kenya
Agricultural Extension services are among the most important rural services in developing countries. The services are considered to be a key driver of technological change and productivity growth in agriculture. In Kenya, like in the rest of the developing economies, agricultural extension has largely been delivered through supply–driven approaches. Due to perceived low impact of agricultural e...
متن کاملUnderstanding the weather signal in national crop-yield variability: Weather-signal in crop-yield variability
Year-to-year variations in crop yields can have major impacts on the livelihoods of subsistence farmers and may trigger significant global price fluctuations, with severe consequences for people in developing countries. Fluctuations can be induced by weather conditions, management decisions, weeds, diseases, and pests. Although an explicit quantification and deeper understanding of weather-indu...
متن کاملTree growth and management in Ugandan agroforestry systems: effects of root pruning on tree growth and crop yield.
Tree root pruning is a potential tool for managing belowground competition when trees and crops are grown together in agroforestry systems. We investigated the effects of tree root pruning on shoot growth and root distribution of Alnus acuminata (H.B. & K.), Casuarina equisetifolia L., Grevillea robusta A. Cunn. ex R. Br., Maesopsis eminii Engl. and Markhamia lutea (Benth.) K. Schum. and on yie...
